This design must predate powder coating. It probably works fine with conventional lube but I don't shoot plain lead in 9mm and I suppose few people do these days.
Once you powder coat it, it will not work in anything other than a 9mm revolver that uses moon clips. My S&W 986 can fire them - but nothing else. The bullet hits the lands and it will not chamber. Not in my PC Carbine, Glock or my Uberti Cattleman 2.
And you cannot seat it deep enough to work, either. Forgetting for the moment the implications of compressing the powder, the bullet simply will not go in far enough. It hits the thicker part of the case and stops, the the rest of the bullet deforms and it hits the lands anyway.
All is not lost. I found that powdercoated this mold makes perfectly good .38 Special roundnose loads.
